Abstract

THE INVENTION CONSISTS OF FORMING AN AQUEOUS SLURRY OF WATER AND PARTICLES OF ORE CARRYING BOTH METALS AND/OR MINERLAS WHICH ARE PASSED AT RELATIVELY HIGH SPEED ALONG AN ELECTRICALLY ISOLATED PATH IN CONTACT WITH ELECTRICALLY INSULATING METERIALS AND IN THE PRESENCE OF AIR.THIS GENERATES A POSITIVES ELECTROSTATIC CHARGE IN THE WATER DROPLETS AND ENCLOSED PARTICLES AND A NEGATIVE CHARGE IN THE ELECTRICALLY INSULATING MATERIALS THROUGH WHICH THEY ARE BEING DRIVEN. THE WATER DROPLETS AND HENCE THE PARTICLES BECOME DIFFERENTIALLY CHARGED SO THAT WHEN THEY PASS OVER AN OPPOSITELY CHARGED NEGATIVE FIELD, THEY ARE DRIVEN INTO THE LOWER OPPOSITELY CHARGED FIELD BOTH BY THE STRONG FORCE OF ELECTRICAL ATTRACTION AND THE RELATIVELY WEAKER FORCE OF GRAVITY. SHOULD THE NEGATIVE COLLECTOR CONTAIN AN AMALGAMATING MATERIAL SUCH AS MERCURY AND THE ORE, AS AN EXAMPLE CONTAIN GOLD, ELECTRONS ARE EXCHANGED PROVIDING INSTANT AMALGAMATION OF THE SURFACE OF THE GOLD. THE ELECTROSTATIC CHARGE IS MAINTAINED THROUGHOUT THE PROCESS UNTIL PRECIPITATION OF THE PARTICLES IS COMPLETED. (FIG.1)
